Answer: The partial pressure of the hydrogen gas is 93.9 kiloPascals.
Explanation:
The partial pressure of the water vapors = 
The partial pressure of the hydrogen gas = 
The pressure measured in the collecting bottle = 
While collecting the hydrogen gas in a collecting bottle with amount of water vapors also get introduced. The total pressure in the collecting bottle will be due to partial pressures of the water vapors and hydrogen.
The partial pressure of the hydrogen gas is 93.9 kiloPascals.
The agar plate with the most countable colonies should be determined by using a colony forming unit (CFU) calculator.
<h3>What is a colony?</h3>
A colony can be defined as a group of visible mass of microorganisms such as bacteria, fungi, that originated (cultured) from a single-mother cell and are grown on a solid agar medium.
In order to determine the most countable colonies, we have to count the total number of colonies by using a hemacytometer and then use a colony forming unit (CFU) calculator to determine the cfu/mL.
<u>Note:</u> You should choose a dilution factor based on the total number of colonies contained in the agar plate.
Finally, input the correct dilution factor into the colony forming unit (CFU) calculator to determine which agar plate has the most countable colonies.

Answer:
Number of moles of methane form = 2.3 mol
Explanation:
Given data:
Number of moles of Hydrogen = 4.6 mol
Number of moles of methane form = ?
Solution:
Chemical equation:
C + 2H₂ → CH₄
Now we will compare the moles of methane with hydrogen from balance chemical equation.
H₂ : CH₄
2 : 1
4.6 : 1/2×4.6 = 2.3 mol
Form 3.6 moles of hydrogen 2.3 moles of methane can be formed.
